What is Martingale Strategy?
Martingale is a position-sizing strategy where the trader doubles their size after each losing trade, theoretically guaranteeing a win that recovers all previous losses plus a profit. The strategy is mathematically unsound for prop firm trading because account size is bounded by the drawdown limit, meaning even a short losing streak can wipe out the account. Virtually all prop firms ban martingale and similar progressive sizing strategies, with AI risk systems flagging the pattern automatically.
